Statement A is correct b. Statement B is correct c. Both A and B are correct d. Both A and B are incorrectThe results of gel electrophoresis of 4 different DNA samples given in the figure. 16 ul was loaded into each well (6 μL diluted DNA* + 8 μL water + 2 μL sample buffer). The ladder is in lane 5, with the size and amount (ng) in each band indicated. *1:5 dilutions of the original DNA sample were made, and the diluted samples were used for AGE. Q. These are the conclusions made about sizes and concentrations of the original (undiluted) DNA samples from lanes 1 and 2. Are these conclusions reasonable? Explain specifically, and if any of the conclusions are not reasonable, explain why not and what should we conclude instead. Sample in lane 1:size is 2.32 kb concentration of original DNA sample is 9.2 ng/ul Sample in lane 2:size is 4.36 kb concentration of original DNA samples is 100 ng/ul Q. The sample in lane 3 was expected to be about 2 kb in size. What is a possible explanation for the results observed?A. Changes and damages to the DNA is permanent and has no remedy.B.
